Keep losing speakers from the system

This problem is very frustrating and seems to be occurring regularly on my system. I have the latest software and keep losing two Sonos One speakers (wireless) from my system. I have an Amp, a Sonos One connected via Ethernet, two Symfonisk and a surround sound (bar, sub, 2 Sonos one), in addition to the two problematic Sonos Ones.These two speakers just disappear from the system. I can see them on the network, but the app can't find them. I notice that one of them (in my bedroom) often reboots during the night (the LED flashes orange and white), but haven't correlated that with the speakers dropping off the network.My Wifi is a Ubiquiti AP, just a couple of months old. Rebooting it seems to fix the problem, but I can't fathom why the AP would be a problem, everything else connected to it works.​Any ideas?
